TURN-TABLE.

Specification oi Letters Patent.

Patented Apr. 20, 1915.

Application filed June 2, 1914. Serial No. 842,435.

To all whom it may concern:

Be it known that I, JOSEPH B. TINSLEY, a citlzen of the United States,residing at Kansas City, in the county of Wyandotte and State of Kansas,have invented certain new and useful Improvements in Turn-.

what are termed turn-tables of the type used in connection with railwaysfor turn ing or reversing the position of locomotives.

The invention has far its object, primarily, to provide for actuatingorturning the turntable by the action or movement of the locomotive, thusavoiding doing this manually as heretofore. I

A further object is to provide also for freeing or unlatching theturn-table preliminary to turning the same, also to again effect thelatching or retention of the turntable in position, as againstunauthorized movement or turning, and to provide for doing this from thelocomotive.

A still further object is to carry out the aforesaid ends with facilityand expedition, and in the minimum time, devoid the man- 'ual labor orexertion of turning the turntable. p

The invention consists generically of means adapted to enable theturning of the turn-table after the locomotive has been run upon thetable by the subsequent further movement of the locomotive thereon,carrying the turn-table therewith.

The invention consists further of sundry features, as accessories tothat end substantially as hereinafter more 'fully disclosed and definedby the appended claims.

In he accompanying drawing is illustrated the preferred embodiment of myinvention wherein it-will be understood that various changes andmodifications may be made with respect tovthe detailed construction andarrangement of the parts without departing from the spirit thereof, andin which drawing':

' Figure 1 is a'general plan view of my turn-table. Fig. 2 isan'elevational view. Fig. 3 is a sectional elevation thereof, and

Figs. 4 and 5 are transverse vertical sectional views of the same takenupon the lines 44.- and 5 5of Fig. 1, respectively.

In the-disclosure of my invention, I suitably devise a circular track 1and a like inner or concentric-track 2 of considerably less diameter,and above these circular tracks '1 and 2 is mounted a rectangular frame3 upon suitable trucks or wheels 4 and 5 traveling upon the tracks 1 and2, respectively. The wheels or trucks 4 are carried or journaled insuitable bifurcated pendent bearings 6 secured to the longitudinalmembers of the frame fl-coincidently are carried by shafts 7 at theirdiagonally opposite ends suitably journaled upon the underside of. thelongitudinal members of the frame 3 so as to cause their wheels to"travel upon the track 2.

Track-rails 8 alining the railway trackrails 9 are suitably secured orspiked into position upon transverse members 10 of the frame 3 servingin the capacity of ties, it being understood of course that the framestructure together with its carrying wheels or trucks and the circulartracks are all suitably depressed or sunken with respect to the surfaceto effect such alinement of the rails 8 with the track-rails 9.

The wheel-shafts 7 are intergeared by spur-gear pinions 11 secured tosaid shafts, respectively, for their conjoint or mutual rotation, whileone of said shafts has fixed thereto a like pinion 12 of slightlygreater diameter than the aforesaid pinions, and slidably mountedimmediately in vertical alinement with the pinion'12 upon the frame 3is-a longitudinal rack 13 engaged by said pinion, said rack beingheld-in keepers or guides 14 secured to thetransverse members or ties10, the purpose of which rack w1ll be presently apparent.

Opposed edge-spaced apart jaws 15 are suitably or flexibly carried byand adapted to be moved with bars or rods 16 formgaging or receivingtherebetwen the desired wheel-axles or other available part of the loorbores in the ends of the rack 13 so as to turn therein, the. opposite orother ends of 10 with the track 1. The wheels; or trucks 5 tered beveledpinions 22 at right angles thereto, which latter are borne upon theinner ends of shafts 23 suitably journaled upon brackets projecting fromthe frame 3, the opposite ends of said shafts having sundrypivoted-together arm and link-connections, as at 24, 25 and 26 with thesquared or angular ends of the members 16 which carry thelocomotive-axle engaging jaws 15, which latter, together with the rack13, con-v stitute the principal factors in effecting the turning of theturn-table through the movement of the locomotive, which arm and linkconnections are clearly seen, particularly in Fig. 5.

The arms of the connections between the shafts 23 and the jaw-carryingmembers 16, designated as 24: and 26, are fixed with re spect to saidshaft and said member to which they are-connected, respectively,therefore are constant in their movements, or the arcs describedthereby, accordingly controlling the movement of the link 25, the othermember of said connection thus providing for a uniform positive actionof the .jaws 15 directly actuated by said connections. The duplicatingof the lever 7'and adjunctive-parts,

together with the locomotive-axle-engagingjaws 15, it is understood, isto provide for the adaptation of the device for use from either end.

, Foot blocks or locks 27, pivoted laterally to the frame 3 at its endsand adapted to drop into notches 28 produced in sills 29 and catching ortaking thereover, provide for suitably anchoring or retaining theturntable in position, this arrangement also being duplicated for eachend of the turn-table, for obvious reasons. A manually actuated lever 30is suitably fulcrumed laterally to the frame 3 to conveniently controlthe disengaging of the foot block or locks 27 from the sills 29 andreengaging the same with the latter; flexible or stout wire connections31 and 31 being efi'ected betweensaid lever and said foot looks orblocks and said lever suitably equipped with a latch-controlled detent32, said cletent engaging a notched or toothed quadrant 33 suitablyfixed to the frame 3.

From the foregoing description, taken in connection with theaccompanying illustra tion, it is thought that the operation of thedevice has been made fully apparent, it be ing only required to state,possibly, that the locomotive bein run upon the turn-table, therequisite ad ustments are readil made by suitably actuating thefoot-lock control- .ling lever 20 and the jaw-controlling lever 7 forengaging the jaws with the locomotive wheel-axles; the engineer thenrequisitely actuating histhrottle to give the locomotive just sufficientmovement'to cause the rack 13 to suitably engage the pinion 12 whichwill through the gearing 11. effect the turning of the turn-table, thisbeing controlled by suitably actuating the lever 7 releasing the actionof the jaws 15 upon the wheel-axles.

I claim:

1. A turn-table of the type described, equipped with means to providefor the running thereon of a locomotive or engine, means including jawsadapted to engage the locomotive wheel-axles, means adapted to bringsaid jaws into positionto receive said axles, and means to effectconnection between the locomotive and the turn-table whereby, with themovement of the former, the turning of the latter may be effected.

.2. A turn-table of the type described, equipped with means adapted forthe running of a locomotive or engine thereon, means including jaws toengage the locomotive wheel-axles, a member carrying said jaws, meansfor actuating said jaw-carrying member whereby said jaws may be broughtI into such engagement with said wheel-axles, and means geared to thetruck-axles of said turn-table, said jaw-carrying member being adaptedto engage and impart movement to said truck-axle geared means with themovement of the locomotive.

3. A turn-table of the type described,

equipped with means adapted for the running of a locomotive or enginethereon, means including a rack geared to the truckaxles of theturn-table, jaws adapted to en'- gage the locomotive wheel-axles, acarrying member for said jaws adapted to engage and move said racklongitudinally, and manually actuated means for axially moving saidjaw-carrying member for effecting such engagement between said jaws andsaid 10- eomotive wheel-axles with the movement of the locomotive.

4. A turn-table of the type described, equipped with means for running alocomotive or engine thereon, a rack geared to the truck-wheel-axles ofthe turn-table, jaws for engagement with the locomotive wheel-axles, acarrying member for said jaws having one end received within one endofand engaging said rack and an opposite angular end portion, a manuallyactuated lever, a shaft geared to said lever, and link and armconnections between said shaft and said angular efid portion of saidjaw-carrying member whereby the latter may be actuated to effect si chengagement of said jaws with said locomotive Wheel-axles, said rackbeing adapted to effect the actuation of the turn-table" copies of thispatent may be obtained for five cents each, by addressing theCommissioner of Patentzi,
